HDMI Switch 4k@60hz Splitter, GANA Aluminum Bidirectional HDMI Switcher 2 in 1 Out, Manual HDMI Hub Supports HD Compatible with Xbox PS5/4/3 Blu-Ray Player Fire Stick Roku

This how I run my setup, HDMI from my Xbox to the switch; HDMI from the switch to my monitor and HDMI from the switch to my tv. You don't need a splitter just a switch and this is the one that I use https://a.co/d/0d6e3aUL
